Acid-Base & Regulation
This is the normal range for blood pH?
What is 7.35-7.45?
The functional unit of the respiratiory system.
What are alveoli?
The ability of the lung to stretch.
What is compliance?
Gas flows into the lungs.
What is inhalation?
Pressure exerted by surrounding air.
What is atmospheric pressure?
This ion helps maintain normal blood pH.
What is bicarbonate (HCO3-)?
The zone responsible for air exchange.
What is the respiratory zone?
The property that allows lungs to return to original size.
What is elasticity?
What is exhalation?
Pressure within the lung alveoli.
What is intrapulmonary pressure?
Acid-based homeostasis in the respiratory system maintains this.
What is blood pH?
This zone moves air from point A to point B.
What is the conducting zone?
Attraction between like molecules such as water.
What is surface tension?
Inspiration is this type of process.
What is an active process?
Gases move from areas of _____ pressure to areas of _____ pressure.
What is high to low?
These receptors detect CO2, O2, and pH changes.
What are chemoreceptors?
These alveolar cells perform gas exchange.
What are Type I alveolar cells?
This detergent-like substance reduces surface tension in alveoli.
What is surfactant?
Expiration during quiet breathing is this type of process.
What is a passive process?
Pressure found in the pleural cavity.
What is intrapleural pressure?
The process of inspiration and expiration operated through this type of feedback loop.
What is a negative feedback loop?
These alveolar cells produce surfactant.
What are type II alveolar cells?
These immune cells in the alveoli remove unwanted particles and pathogens.
What are macrophages?
Exhalation relies on this gas law.
What is Boyle's Law?
This law states total pressure equals the sum of individual gas pressure.
What is Dalton's Law?
